| CCTV Cabling|
|We are looking at installing a new CCTV system as part of our works when refurbishing/extending a power station. We have to indicte underground cable routes through out the site to present for our site providers approval. As yet we do not have any information on the underlying soil and are unsure if it may aid the degration of the cables over time. Can you give advise on typical lifespans of CCTV cabling and if ducting the cables will hold any advantages in this respect.|

On a critical matter like this I would go directly to a cable manufacturer of your choice and have them provide the estimated lifespan data. I assume that a power station may actually pose its own unique challenges that may affect not only lifespan but also EMI-related noise and you may need the manufacturer's help in addressing those additional issues. I can also imagine that on a power station in some cases you cannot even use a conductive CCTV cable (except for powering the cameras of course) and will have to use fiber optic cable instead.
In any case, I am pretty sure you will be able to find a cable manufacturer that will help your design team, especially if the project is big enough.
